BOTTLE STOPPER.

Application led July 31, l1926, Serial No. 126,208, and in lungary November 10, 1925.

My invention relates to bottle-stoppers comprising an expansible plug adapted to be pressed, by means of a screw, against a body supported by the edge of the bottlemouth, such longitudinal compression of the plug causing Ahermetic engagement vbetween the bottle-neck and the plug owing to the transverse expansion oi the latter.

The object of the invention is to provide a simple and convenient construction, in which especially the screw-bolt is prevented from dropping into the bottle. with the parts assembled in such a manner that the expansible plug, ii worn or damaged, may

l5 be replaced without using any tool.

der to cause the screw-bolt, when entirely unscrewed, to be caught by the body supported by the edge ot the bottle-mouth, I enlarge the threaded end portion of the bolt over the width ot the central openingprovided in said body for the reception ot the screw-bolt, and, in the side of the body supported by the bottle-mouth, I providean aperture which will allow the screw-bolt to be introduced laterally.

A constructional form of the invention is shown, by Way of example, in the accompanying drawingsin which- Fig. 1 is a sectional elevation of niy iinproved bottle-stopper; u

Fig. 2lis a plan view of the saine;

Fig. 3 is a detail view showing a bow forming the wings for operating thescrewnut;

Fig. 4 is a central longitudinal section of the body supported by the edge of the bottlc-mouth and against which the plug is pressed in order to be expanded;

Fig. 5 is the plan ot the same body with .0 the moietycut in a horizontal plane.

The expansible plug consists of a rubber ring l surroundingthe unthreaded portion of the screw-bolt 2 which is provided with alarge head at its inner end. The body 5 against whichthe plug 1 is pressed consists of a metal cap 4 with a rim or flange resting on they edge of the bottle-mouth.

The nut 3' for operating thescrew is lo-I cated within the cap 4. Wings for operat- L0 ing the nut 3 are formed by a bow 6 which is secured by means of a pivot 5 so that it may be laid down as indicated in Fig. 2 by dotted lines.

According to the invention, the threaded l5 end of the bolt 2 has a somewhat larger diameter than the plain portion thereof,l

In orn the central opening 7 in the bottom of the cap 4" having a diameter between those of the plain and threaded portions of the bolt 2. In order to enable the bolt2 to be introduced into the opening 7', I provide the cap 4 with a lateral aperture 8, Fig. 4, having a width surpassing the diameter of the threaded portion of the bolt. 2 and beingconnected with the central opening 7 by a radial slot 9 in the bottom ofthe cap 4, Fig. 5, the width ot' this slot corresponding to the diameter of a `short neck 10 of the bolt 2 close below the threaded portion.

What I claim isl. A bottle-stopper consisting of a body supported by the edge of the bottle-mouth and project-ing into the bottle-neck and having aYcent-ral opening,fa bolt fitting into said central opening and 'having a head at its inner end and a threaded portion at its outer end `with a diameter ,greater than that of said central opening. an expansible plug upon said bolt between its head and said body,yand a nut adapted to be screwed upon the threaded end portion of said bolt, a lateral aperture provided iu said body and connected with said central opening al1 said central opening, and ashort neck por tion formed below said /threaded portion with a diameter smaller than that of said central opening, a rubber ring upon said bolt between its head and the bottom of said cap, and a` screw-nut fitting upon the threaded end portion of said bolt, said eylindrical side wall ofsaid can being provided With an aperture so formed as to allow said threaded end portion of said ybolt to pass through and connected with said central opening by a radiall slot of such a width as to let through only the neck portion of said bolt.

' In testimony of 'which I hereunto axiny signature.

`Husain LINNER.
